AIB. SEPARATOR.

Application -le'd June 18,1928 Serial No. 645,943.

The invention relates to an improved separator. .for removing foreign substances such as particles-ofoil, water and other foreign substances' from air, and its primary object isto provide a light, portable separator of the above character which canbe connected directly into the compressed air supply Aline such as 'a flexible hose leading to adevice requiring dry and clean air, for-example, a pneumatic paint brush'.

A further'object is to provide an inexpensive airseparator which isr sturdy and simple in construction, which is not readily injured by rough usage, and which. canbe' easily 'eicient .20 In the .accompanying drawings, Figure 1 spool Further obiects and adtaI-lt'ages will .be-

While m'yinvention is susceptible of varidrawings and will herein describe in detail 'the preferred embodiment, buti it should be understood that Ido not thereby intendto -limit the invent-ion 'to the-( letailedillustra-- tion, but aim in the' subjoined claims to cover all inodications and alternative. constructions' falling withinthe Scope of the invention. f

threaded thereon. Leather gaskets 13 posi-- tioned between thefheads and the end edges of the cylinder l()` serve to make the connections air tight. The head' 11 is-provided with athreaded intake passage 14, andthehead 12'is provided with' a threaded exhaust passage 15 to which the severed or separated ends of the-.air` hose (not shown)`may-be 'attached.

The exhaust passage .15 Connects at its4 inner end. with a' restricted passage 16 extending through a cylindrical lug 17 formed Fig. 2 is a detailI view showing the strainer 3 is aviewvtaken inthe plane of line.

on the inner side of the head 12. The lug 17 is threaded into the end of a tube 18 which extends centrally through approximately two-thirds of the length of the cylinder 10, and which forms part of a strainer spool 19.

Rigidlyv mounted on the tube 18. are two spaced disks 20, which form two free chambers 21 andv 22 in opposite ends of the cylinder 10. Each disk 20 fits snugly within the cylinder 10, and is provided with a large number of small perforations 23. The space between the disks is filled by 'a screen 24, comprising iny the present instance, a Strip of copper wire clot-h wound around the tube 18. A screen of this character eiiicientlyre- I moves allforeign Substances .Suspended in the air, and can 4be 'easily cleaned, as by burning oz' said substances or by washing the screen in a suitable cleaning liuid. The

chamber 22`communicates with the interior of the tube 18 and thepassage 16 through a plurality of openings 25 formed in the wall of the tube.

' Air from theintake passage `14 passes into the cylinder 10 through an elongated intake nozzle 26 threaded into 'a' lug -27 -ormed on the inner` side of the head 11. The nozzle 26,*whichA is provided .with a small restricted air passage 28 extends cenousmodiications, I have illustrated in the trally into the open end of the tube` 18 to almost the `remote end of the screen 24. A plug 29, preferably .made of brass, is soldered or otherwiseseeured in the tube 18 just beyond the free end ot` the nozzle 26, Iand serves to sharply defiectthe air leaving the passage 28 outwardly around the nozzle 26 into the chamber 21.. The condensate within the cylindermay be removed through a cock 30 threaded through the head 11.

' Upon leaving. the restricted passage' 28,`

thecompressed air is suddenly expanded with the result that its temperature is low- 'ered and a portion of the entrained liquids 'pact against the plug 29 and the subsequent sharp .turnof the. air, eiect a further precipitation ofthe moisture suspended therein. From the vchamber21, the air passes through and .vapors are condensed. 'Thefsudden imthe perfo ra tions g23 in the disks 20 and trained in the air.

I claim as my invention:

1. An air separator having, in combination, a cylindrical shell, heads closing the ends of said shell, a high pressure intake nozzle having a long restricted passage and supported by one of said heads, a tube supported by the other head and surrounding said nozzle, a plug closing said tube positioned to intercept the flow of air at a point just beyond the end of said nozzle, a pair of spaced perforated disks `mounted on said tube, a screen filling the space between said disks, and an air exhaust passage last mentioned head.

Q. An air separator having, in combination, a shell, a pair of heads closing opposite ends of said shell, said heads each having ahollow tubular projection on their inner faces communicating respectively with the inlet and outlet passages, a pair'oi'tubes secured to said projections and communioat ing with said passages, said tubes telescoping loosely `and one tube having a narrowre strioted admission in the outer tube irectly before said passage, an aperture in said outer tube oom'- municating with the outlet passage beyond in said assage,`a plug mounted l said plug, and spool means having an air A filter mounted on said outer tube.

In testimony whereof, I have hereunto affixed my signature.
